<b><i>Aim:</i></b> Myocardial ischemia/reperfusion (I/R) injury is a severe trauma that cells undergo and associated with cardiomyocyte apoptosis. Recently, miRNAs have been demonstrated to play an important role in cardiovascular biology disease. However, whether the miR-133a ER stress hydrogen sulfide (H<sub>2</sub>S) protection of cardiomyocytes against I/R-induced apoptosis remains unclear. <b><i>Methods:</i></b> The neonatal...
The advanced glycation end products (AGEs) are associated with increased cardiac endothelial injury. However, no causative link has been established between AGEs and enhanced injury after ischemia/reperfusion. More importantly, the molecular mechanisms by which may increase remain unknown. Adult rat microvascular cells (CMECs) were isolated incubated AGE-modified bovine serum albumin (BSA) or BSA. After AGE-BSA BSA preculture, CMECs subjected to simulated ischemia (SI)/reperfusion (R). SI/R...
The receptor for advanced glycation end products (RAGE) and thioredoxin (Trx) play opposing roles in diabetic myocardial ischemia-reperfusion (MI/R) injury. We recently demonstrated nitrative modification of Trx leads to its inactivation loss cardioprotection. present study is determine the relationship between augmented RAGE expression diminished activity pertaining exacerbated MI/R injury heart. state was induced mice by multiple intraperitoneal low-dose streptozotocin injections....

Serum detected subjects by reverse transcription-quantitative real-time...
Objective: Recent clinical observations have indicated that nonlethal mechanical trauma significantly increases myocardial infarction risk even in the presence of completely normal coronary arteries. We investigated molecular mechanisms responsible for exacerbation ischemic injury after with a special focus on role tumor necrosis factor α and its potential downstream effector adiponectin, novel adipokine anti-inflammatory cardioprotective properties. Design: Laboratory study. Setting:...
As zoom motion is common in video applications, a linear model derived to describe based on the analyses of camera imaging principles. Based model, vector predictor for videos involving proposed.

The present study determined the dynamic change of adiponectin (APN, a cardioprotective adipokine), its receptor expression, and their impact upon myocardial ischemia/reperfusion (MI/R) injury during type 1 diabetes mellitus (T1DM) progression, involved underlying mechanisms. Diabetic state was induced in mice via multiple intraperitoneal injections low-dose streptozotocin. plasma APN concentration cardiac receptor-1 -2 (AdipoR1/2) expression were assessed immediately after onset (0 wk) 1,...
Thel-type Ca(2+)current (ICa,l) plays a crucial role in shaping action potential and is involved cardiac arrhythmia. Statins have been demonstrated to contribute anti-apoptotic anti-arrhythmic effects the heart. Here, we examined whether atorvastatin regulates theICa,land cell injury induced by angiotensin II (AngII) as well putative intracellular cascade responsible for effects. Cultured neonatal rat ventricular myocytes were incubated with AngII 24 h, then expression levels of...
Both temporal prediction and inter-view are employed to improve the coding efficiency in multiview video coding. Hierarchical B pictures usually used as basic structure for prediction. The each hierarchy level brings different improvement entire efficiency. We propose a scalable which would be disabled if picture redundancy can almost exploited by intra In this way, time-consuming computation of disparity estimation saved. Experimental results show that lower encoding complexity, smaller...
Up-regulation of angiotensin II (AngII) occurs in cardiac diseases, such as congestive heart failure, hypertrophy, myocardial ischemia and atrial fibrillation, which represent major health problems. Evidence from vivo studies suggests that the level Apolipoprotein-J (ApoJ) is also elevated but plays a protective role cardiovascular disease. This study aimed to evaluate effects ApoJ against cytotoxicity AngII neonatal rat ventricular cells (NRVCs). In culture, NRVCs were damaged by exposure...
Currently, endoplasmic reticulum stress is studied utilizing a dephosphorylation inhibitor (Sal). The traditional Chinese patent medicine and simple formulation Shensong Yangxin Capsule commonly used medication for the treatment of arrhythmia. However, efficacy underlying mechanism capsule in treating post-ischemic heart failure myocardial tissue have not yet been investigated.
Building on the argument that change of motion states attracts more attention than itself, this letter develops a novel method for key-frame extraction based acceleration vectors. Different from traditional methods using maximal or minimal energy, proposed uses states, in magnitude and phase, main moving objects as metric extraction. Experimental results show although similar objective performance is achieved by to with widely used key frames extracted are consistent human perception.
Abstract Background Cardiac Ca 2+ /calmodulin-dependent protein kinase II (CaMKII) activation plays a critical role in cardiomyocyte (CM) apoptosis and arrhythmia. Functional ATP-sensitive potassium (K ATP ) channels are essential for cardiac protection during ischemia. In cultured CMs, L5 low-density lipoprotein (LDL) induces QTc prolongation. is highly electronegative atherogenic aberrant form of LDL, its levels significantly higher patients with cardiovascular-related diseases. Here, the...

Oxidized low-density lipoprotein (ox-LDL) is crucial in cardiac injury. Apolipoprotein-J (ApoJ) contributes to antiapoptotic effects the heart. We aimed evaluate protective of ApoJ against ox-LDL cytotoxicity Neonatal rat ventricular cells (NRVCs). NRVCs were damaged by exposure ox-LDL, as shown increased caspase-3/7 activity, enhanced caspase-3 expression, and decreased cell viability. overexpression, using an adenovirus vector, significantly reduced ox-LDL-induced also prevented from...
